Well it's time for bed from night one of the tournament... whew...
Feedback: Very. Very. Fun.
In about 5-6 hours had the pleasure of being part of 30 different battles.... I don't think I had to click "Start Battle" more than three times to leap into combat... Some people I knew... but lots of new faces. Talked to most of them and their experiences. In general Izcers seemed to enjoy the access to all of the cards (though the $$$ issue did pop up now and then).
and TONS of dragon decks... maybe 4/5 of the battles revolved completely/partly around a dragon.
I also saw some unique setups for SS... and the flexibility was terrific (I learned quite a bit). Since you had NO idea what was in the other Izcers's deck (having access to all cards) I found myself seeing combinations I would like to use personally for the Arena. There were some predictable strategies... but I saw them "switched up" several times to create confusion.
(I'm curious though if some of the participating accounts were multis trying out different decks* ... saw several with 1500 RP level 2-6 and a great handle on battle dynamics)
*I do wish we had spots for several files during "ALL card" tournaments. It would help with tweaking your decks and trying out new ones without losing your original file.
Perhaps a "Non-star" (play without worry of losing all your stars) ALL card tournament in the future with multiple file spots? Maybe a small program that would compare the all card tournament file you've created versus the cards you currently own? (to see what you still need to collect)
